A copper-catalyzed one-pot synthesis of functionalized benzimidazoles has been developed. The procedure combines the copper-catalyzed three-component cascade reaction of sulfonyl azides, alkynes and 2-bromoaniline and the copper-catalyzed intramolecular N-arylation of sulfonamides in one sequence, which afforded the products in moderate to good yields.
已经开发了铜催化的一锅合成功能化的苯并咪唑。该程序将铜催化的磺酰叠氮化物,炔烃和2-溴苯胺的三组分级联反应与铜催化的磺酰胺的分子内N-芳基化反应结合在一起,从而以中等到良好的产率提供了产物。
